Bone: Anterior superior iliac spine
The obturator membrane. (Anterior superior iliac spine visible in upper left).
Location of McBurney's point (1), located two thirds the distance from the umbilicus (2) to the anterior superior iliac spine (3).

The anterior superior iliac spine (ASIS) is an important landmark of surface anatomy. It refers to the anterior extremity of the iliac crest of the pelvis, which provides attachment for the inguinal ligament and the sartorius muscle.

ASIS provides a clue in identifying some other clinical landmarks, including:

1. McBurney's point
2. Gardner's line
3. Inguinal ligament

A - Anterior (front, like the face)
S - Superior (towards the head, opposite to feet)
I - Iliac (Pelvis bone)
S - Spine
